Specification forming part of Letters Patent .No. 133.066, datedNovember 12, 1872.

. thereon, to be afull, clear, and exactdescription of the same, andwhich said drawing constitutes part of this specification andrepresents, in-

Figure 1, a front view; Fig. 2, a sectional side view; and-in Fig. 3, avertical longitudinal section on line a; w.

o a I This mvention relates to an improvement a in machines for formingbullets by the process of swaging-that is to say, a machinein which alead blank is swaged intothe form required for the bullet. In this classof machines it is necessary that there been opening in the-die orfollower through which the surplus lead may escape; but thisnecessitates the trimmin g of such surplus lead from the bullet after itis formed; The object of this invention a primarily is to allow for thisescape audhtrim the surplus lead from the bullet while in the die; andit consists in forming a vertical perforation in the follower eccentricto the center, into which perforation the surplus lead will pass, andafter the follower hasperformcd the work of compression, a partialrotary movement is imparted thereto, which causes the follower to turnupon the end of the bullet, and the perforation, which is eccentric tothe axis of the follower, turns out of position where the surplusentered and cuts from the bullet the surplus which it contains, thusallowing the bullet to be dischargedlfrom the machine complete andperfect. My invention also consists in the mechanism hereinafter de-.scribed for supplying the blanks for the oper-;

ation of the follower.

A is the bed of the machine, within which,

at .a, are. arranged the usual dies for form-- in g the bullet. i Abovethis, in suitablebearings B B, is arranged the follower G, and to whicha vertical movement is imparted from the driving-shaft 0 through a crankand 1ever, 0 or otherwise, so that a blankbeingplaced in the die and thefollower fordedthereon will compress the bullet in the usual manner. Inthe lower end of this follower I form a vertical perforation, oropening, d, (see Figs. 2 and 2%) this perforation being eccentric to theaxis of the spindle, and opening out at some point above, as denoted inFig. 2. To this follower at the proper time, as hereinafter described, arotating movement is imparted by means of a cam, D, actuating a slide,D, (see Figs. 2 and 2**;) the said slide in moving back and forth beingin connection with the follower causes it to rotate accordingly. As thefollower strikes the lead blank and compresses it the lead, more than isrequired for the bullet, will be forced up through the perforation d inthe follower until a bullet. is

completely formed, then the before-mentioned rotary movement is given tothe-follower, causing it to turn upon the end of the bullet, and as theperforation'd is eccentric to the axis of the follower this perforationis car-- ried off from this point on the bullet, and in so doing cutsthe surplus which is in the perforation smooth and clean from thebullet,

then the ball is discharged in the usual mam ner. Thus the bullet iscompleted, and comes from the machine requiring no furtheroperation. v

To automatically supplythe blanksfor the action of the follower, aslide, L, 'is arranged longitudinally on the machine in suitable guides,and actuated by suitable mechanism to impart a longitudinal movementthereto, here represented as from acrank-wheel, N, the said slide fittedwith an opening, b, as seen in Fig. 3, to receive the blank in oneposition, and by its longitudinal movement to carry this blank beneaththe follower to deliver the blank to the die. With this slideis combineda vertical tube, P, denoted in solid black, Fig. 3, this tube extendingto near the mouth of a hopper, it. Over this is a sleeve, S, arrangedrto slide freely on the tube P, and is in connection, by an arm, T, withthe follower, so that as the follower-rises and falls this sleeve risesand falls with it. The upper end of the tube 1? is formed or cut at anangle, as seen in Fig.

3, leaving no point upon which a blank may rest. The sleeves passing upand down over the end of this tube, as denoted in broken l1nes,F1gs. 2and 3, constantly agitates the mass of blanks in the hopper around theend 'of the tube, thus causing the blanks to follow each othersuccessively into the tube P. This tube P stands directly over theopening b in the slide L, so that when the opening comes beneath thetube it takes a blank therefrom and transfers it to the die, thenreturns for a second, and so on. I

I have represented the follower as having a reciprocating and. rotatingmovement with stationary dies but it will be evident to those familiarwith machinery of thischaracter that the same result will be attained bya station ary follower and reciprocating and rotating die, or thesemovements may be imparted to one or the other, or both.

I claim as my invention .1. In a machine for swaging bullets, consistingof the follower C and the usual die, one or either or both having areciprocating movcment, the perforation d in the follower, combined withmechanism 'to rotate the said follower, substantially as and for thepurpose set forth.

2; In combination with a follower and die for swaging bullets, I claimthe tube Pjan'd reciprocating sleeve S and slide or carrier L,substantially as and for the purpose set forth.
